Lobes and Major Sulci of the Cerebral Cortex in Neuroanatomy

The cerebral cortex is organized into four lobes—frontal, parietal, occipital, and temporal—that are demarcated by major sulci: the central sulcus separates the frontal from the parietal lobe, the parieto-occipital sulcus separates the parietal/occipital regions from each other and from the temporal lobe, and the lateral sulcus (lateral fissure) separates the temporal lobe from the frontal and parietal lobes. This is a concept within neuroanatomy, providing the foundational topographic map used to describe cortical regions and their boundaries.
